Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

Quantum information processing relies on the precise control of non-classical states in the
presence of many uncontrolled environmental degrees of freedom. The interactions …

Superposition, entanglement and non-locality constitute fundamental features of quantum
physics. The fact that quantum physics does not follow the principle of local causality,–can …

Superconducting qubits are leading candidates in the race to build a quantum computer
capable of realizing computations beyond the reach of modern supercomputers. The …

The aim of this review is to provide quantum engineers with an introductory guide to the
central concepts and challenges in the rapidly accelerating field of superconducting …

Since the first observation of coherent quantum behaviour in a superconducting qubit, now
more than 20 years ago, there have been substantial developments in the field of …

Full manipulation of a quantum system requires controlled evolution generated by nonlinear
interactions, which is coherent when the rate of nonlinearity is large compared with the rate …

Scaling is now a key challenge in superconducting quantum computing. One solution is to
build modular systems in which smaller-scale quantum modules are individually constructed …

Quantum information is vulnerable to environmental noise and experimental imperfections,
hindering the reliability of practical quantum information processors. Therefore, quantum …

Just as “classical” information technology rests on a foundation built of interconnected
information-processing systems, quantum information technology (QIT) must do the same. A …
